[PATCH] gcc.misc-tests/linkage-y.c: Compatibility with C99+ system compilers

[Florian Weimer]

This program is compiled with an installed "cc" compiler, not the
built GCC compiler, so it should be as compatible as possible across a
wide range of compilers.

gcc/testsuite/

        * gcc.misc-tests/linkage-y.c (puts): Declare.
        (main): Add int return type and return 0.
